BEST MODE

Hereinafter, the above and other objects, features and advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, a tablet discharge chute according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals are used throughout the different drawings to designate the same or similar components, unless specifically mentioned otherwise.

Configurations of a tablet discharge chute according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2, and operation of a separation part will be described with reference to FIGS. 3 to 5.

The tablet discharge chute according to the embodiment of the present invention includes a separation part coupled to a shaft between a main channel into which tablets are inserted and a plurality of discharge channels for separating and discharging the inserted tablets so as to switch discharge paths for tablets. When the shaft rotates, the separation part lifts tablets being discharged from the main channel to close a first discharge channel having been opened. Simultaneously, a second discharge channel having been closed is opened to guide the lifted tablets to the opened second discharge channel. Consequently, discharge paths for tablets are switched without jamming tablets between the separation part and the main channel.

As shown in FIGS. 1 to 5, the tablet discharge chute includes a channel unit 100, a separation part 200, and an actuator 300.

The channel unit 100 includes a main channel 110 formed as one channel into which tablets are inserted and first and second discharge channels 120 and 130 extending in one piece from a lower end of the main channel, the first and second discharge channels separating and discharging the inserted tablets.

Here, the first and second discharge channels 120 and 130 may be provided as a plurality of separate channels communicating with the main channel 110. Alternatively, the first and second discharge channels 120 and 130 may be provided with a partition 125 in a longitudinal direction at the middle therebetween at which the width of the channel unit is enlarged from the lower end of the main channel 110.

Also, the width of the main channel 110 may be equal to the total width of the first and second discharge channels 120 and 130, or as shown in the drawings, the width of the main channel 110 may be formed to be smaller than the total width of the first and second discharge channels. It is desirable that the width of the main channel is equal to the width of each of the first and second discharge channels 120 and 130.

As shown in FIG. 1, between the main channel 110 and the first and second discharge channels 120 and 130, the separation part 200 is coupled to a shaft 210 as being perpendicular to the main channel 110 and the discharge channels 120 and 130. On the shaft 210, first and second separation plates 220 and 230 are coupled at a predetermined angle therebetween.

As shown in FIG. 2, the first and second separation plates 220 and 230 are coupled on the shaft at an included angle (θ) less than 180° therebetween. It is desirable that the first and second separation plates 220 and 230 are provided with the included angle (θ) ranging 120° to 150°. Also, the first and second separation plates 220 and 230 are placed to face the discharge channels 120 and 130.

The actuator 300 is coupled to the shaft of the separation part, and is operated to apply torque to the separation part 200. The actuator 300 is electrically connected to a controller (not shown), and the controller controls the actuator to rotate the separation part at a preset angle.

Furthermore, at an intermediate area between the main channel 110 and the first and second discharge channels 120 and 130, a guide 400 is provided to guide tablets inserted into the main channel 110 to the first separation plate 220 or the second separation plate 230 of the separation part.

Here, the intermediate area between the main channel 110 and the first and second discharge channels 120 and 130 is placed above the central axis 210 of the separation part 200, and thus the guide 400 provided at the intermediate area is placed above the central axis 210 of the separation part 200.

Also, the guide 400 is provided at a slope angle that is equal to a slope angle of the first separation plate 220 in a case where the first discharge channel 120 is closed or to a slope angle of the second separation plate 230 in a case where the second discharge channel 130 is closed.

Also, the guide 400 is provided to overlap an end of the first separation plate 220 or an end of the second separation plate 230 by a predetermined portion. That is, a movement path of tablets sliding on a slope surface of the guide 400 is naturally connected to the first separation plate 220 or the second separation plate 230.

Furthermore, the guide 400 is provided at a location spaced apart from the end of the first separation plate 220 or the end of the second separation plate 220 of the separation part by a preset distance in a longitudinal direction.

The guide 400 is provided to be spaced apart from the first separation plate 220 and the second separation plate 230 because in a case of switching discharge paths, in consequence of a rotation direction of the shaft, the first separation plate 220 or the second separation plate 230 rotates in a direction of lifting tablets being discharged from the main channel 110 such that the first separation plate 220 or the second separation plate 230 becomes close to the guide 400 by being rotated at a preset angle. Here, since tablets on the first separation plate 220 or the second separation plate 230 may be jammed between the guide 400 and the first separation plate 220 or the second separation plate 230, a space between the guide 400 and the first separation plate 220 or the second separation plate 230 is provided such that tablets descend on the slope surface of the first separation plate 220 or the second separation plate 230 and are discharged through the opened discharge path without being jammed between the guide 400 and the first separation plate 220 or the second separation plate 230.

As shown in FIGS. 3 to 5, the tablet discharge chute discharges tablets supplied from a tablet press by separating tablets into normal, damaged, and sample tablets. The accompanying drawings illustrate tablets discharged by separating normal and sample tablets.

As shown in FIGS. 3 and 4(a), the first separation plate 220 of the separation part 200 closes the first discharge channel 120 and the second separation plate 230 is vertically positioned at the middle between the plurality of discharge channels to open the second discharge channel 130. Tablets discharged from the main channel 110 are discharged through a normal tablet discharge path of the opened second discharge channel 130.

As shown in FIGS. 4(b) and (c), in a case of switching discharge paths, when the actuator 300 is operated to rotate the shaft 210, the first separation plate 220 of the separation part rotates toward the discharge channel 120 (state of (b)) and is vertically positioned at the middle between the first and second discharge channel 120 and 130 to open the first discharge channel 120. The second separation plate 230 in cooperation therewith lifts tablets being discharged such that the second discharge channel 130 is closed. Here, tablets on the second separation plate 230 descend on the slope surface of the second separation plate 230, and are discharged through the opened the first discharge channel 120.

Reversely, as shown in FIG. 5(a), the second separation plate 230 of the separation part closes the second discharge channel 130 and the first separation plate 220 is vertically positioned at the middle between the plurality of discharge channels to open the first discharge channel 120. Tablets discharged from the main channel 110 are discharged through a sample tablet discharge path of the opened first discharge channel 120.

As shown in FIGS. 5(b) and (c), in a case of switching discharge paths, when the actuator 300 is operated to rotate the shaft 210, the second separation plate 230 of the separation part rotates toward the discharge channel (state of (b)) and is vertically positioned at the middle between the plurality of discharge channels to open the second discharge channel 130. The first separation plate 220 in cooperation therewith lifts tablets being discharged such that the first discharge channel 120 is closed. Here, tablets on the first separation plate 220 descend on the slope surface of the first separation plate 220, and are discharged through the opened second discharge channel 130.

As described above, according to the present invention, the first and second separation plates of the separation part for switching discharge paths are arranged at the included angle (θ) less than 180° therebetween to face the discharge channels. When the actuator is operated to rotate the separation part, the first discharge channel having been opened is closed by lifting tablets being discharged from the main channel. Simultaneously, the second discharge channel having been closed is opened to guide the lifted tablets to the opened second discharge channel. Consequently, tablets can be prevented from being jammed and destroyed such that malfunction of the separation part can be avoided, whereby desired accuracy and speed of tablet separation can be ensured.

Although the preferred embodiments of the present invention have been disclosed, the present invention is not limited to the aforementioned particular embodiments. That is, those skilled in the art will appreciate that various modifications and changes are possible, without departing from the scope and spirit of the present invention as disclosed in the accompanying claims.
